PURPOSE:To execute manual operation by small force by detaching a feedback device from a driving controlling means for a feed shaft on operation by a handle. CONSTITUTION:When a feed shaft 4 is operated manually by a handle 6, the driving of the feed shaft of a servomotor 5 is released by turning a power supply switch (not shown) for driving the motor 5 OFF. When a hand touches with the handle 6, a touch sensor 12 detects the touch and turns a switch 9 OFF. Accordingly, a tacho-generator 8 and a controller 10 are detached, and feedback control by the tacho-generator 8 is also released. |
